I don't want to be a Chicken Little, and I could certainly be wrong...

When we have a laundry list of catastrophes lined up... its really hard to be wrong.
Like flipping heads 15 times in a row. It could happen,...

However, the odds are more like 90-99% positive each catastrophe will happen.

Even with the Covid... here, the earth HAD TO stop and take a break and reassess their lives / livelihood.
This could have been WW III that did that. But, we had a lockdown, for a "virus" that was more hype than real.
What i am saying, is we still had something world changing, but it could have been much worse.
We flipped heads at least 14 times in a row.

So, if you are not already @papa-pepper then you really have to choose radical life changes.
Growing a little garden isn't going to cut it.
Moving from the city to the suburbs isn't going to cut it.

You will need to grow all your food in a greenhouse, or you will starve.
I would say we have about 10 years. So, get a five year plan, and start enacting it.
